Electric condensate pump design analysis and operation introduction
February 24 21:07:03, 2024
Condensate pump is a vertical double-shell tubular bag shell structure, the first round of single suction or double suction form, the secondary impeller and the final stage impeller universal, single-suction form. Xiao Bian today to introduce the electric condensate pump under the design analysis and operation of the introduction. Condensate pump Condensate pump conveying medium characteristics Conveying medium: Condenser condensate; pH value (25 ℃) 8.5 ~ 9.2; hardness ≤ 1.5umol / L; dissolved oxygen ≤ 15umol / L. Cooling medium: Condensate pump If there is a seal problem, the pump bearing preferentially uses water cooling. Condensate water temperature: Design 44 ℃, maximum 55 ℃; Factory power supply voltage: high voltage 10kV, low voltage 380V. Condensate Pump Equipment Use Continuous pumping of hot water from the condenser. Each unit with 2 sets of 100% capacity condensate pump, a normal run, a standby, if the operation of a failure, the backup pump starts immediately. Condensate pump without front pump, bidder consider effective measures to prevent cavitation. Condensate pump flow requirements Hot water wells maximum flow t / h - condensate pump design point as the maximum flow conditions point; the water pump running time the longest probability of running in the region, the efficiency is guaranteed. Select a working point in the region as the condensing water pump operating point of economic operation, the operating point as condensate pump efficiency assessment point; Condensate pump minimum flow: pump minimum flow does not exceed 25% of rated flow, Calculations or substantive statements (including performance curves) on how to determine the minimum flow rate before delivery in the tender.
